[TenTec] Brand new Omni 7 broke already

[Bob McGraw - K4TAX]

Having found it necessary to replace one of my encoders, I took it on myself 
to see exactly why the other one failed.  There is a rubber or synthetic 
material ring inside that is used to provide damping and provide a seal to 
the shaft from the outside world.  I found this ring had basically "balled 
up" or galled in its race around the shaft causing the shaft to bind.  Then 
the mis-alignment of the shaft caused the wiper on the segmented control to 
also become mis-aligned.

To me this is a quality issue with the manufacture of the control and is one 
not likely to show up until some time later.  Thus just as reported.

Now with all that said, the new encoder has been in the radio for some time 
and still shows a nice degree of dampening on rotation but no other issues.
